The list below shows the characters/states that support, as synapomorphies, each clade discussed in the present contribution.
Anhangueroidea - 4 synapomorphies: character 165(1), presence of a palatal ridge (tapering anteriorly); 177(1), reflected palatal tip, with first upper alveolus facing anteroventrally; 226(1), presence of an individualized mandibular groove; and 312(1), lateral offset of the third alveolus (both jaws).
Targaryendraconia - 6 synapomorphies: 35(1), jaw anterior ends lateral margins subparallel; 228(1), median dentary groove deep and narrow (subequal to half of the alveolar width); 233(1), dentary symphysis anterior end laterolaterally compressed (about three times alveolar width in total, inclusive of the alveoli); 255(1), dentition extending for over 70% total jaw length; 259(1), dentition spacing approximately even along jaws; 303(1), bony bar separating the first pair of alveoli thin (half of alveolar width or less).
Targaryendraconidae - 4 synapomorphies: 218(2), dentary symphysis anterior region with convex occlusal surface; 227(1), dentary groove extending at the level of the first pair of alveoli (but not to the rostral tip); 229(1), dentary groove lateral rims conspicuously raised above alveolar margin; 301(1), enlarged lower first tooth (larger than the second).
Cimoliopteridae - 5 synapomorphies: 71(1), presence of a rhinoid process (“nose-like” anterior protrusion of the rostrum above the first alveoli); 167(2), palatal ridge anterior end reaching a level between the second and third pair of alveoli; 303(1) first pair of alveoli separated by a laminar sheet of bone; and 305(1), first three pairs of alveoli closely packed together.
Anhangueria - 2 synapomorphies: 59(1), lateral expansion of the anterior jaw tip (forming a rosette comprising 4-5 laterally offset alveoli); 431(1), prominent humeral supracondylar process.
Hamipteridae - 3 synapomorphies: 93(1), premaxillary crest striated in texture; 95(1), premaxillary crest anterior striae and sulci well-defined and curved in shape; 85(1), premaxillary crest with an anterodorsal expansion.
Anhangueridae - 8 synapomorphies: character 89(1), premaxillary prenarial crest close to rostral tip; 126(1), frontal crest; 129(1), presence of parietal crests; 135(0), broad lacrimal process of the jugal; 144(0) jugal contact with lacrimal in the ventral half of the orbit; 182(1), deltoid facet with first upper alveoli mostly (or totally) dorsally surpassing second upper alveoli; 234(2), presence of a sagittal dentary crest; 310(1) second upper alveolus anteroposterior axis markedly more anterodorsally inclined than subsequent alveoli; and 387(0), symmetric sternocoracoid articulations.
Tropeognathinae - 4 synapomorphies: 60(0), lateral expansion of the anterior jaw tip relatively narrow (under 130% the width of the posterior constriction); 96(1), premaxillary crest anterior margin level with rostrum tip; 282(1) relatively stout premaxillary teeth (length no more than 4 times width); and 303(1), upper alveoli 4 and 5 smaller than 6.
Coloborhynchinae - 7 synapomorphies: character 61(1), lateral expansion of the anterior jaw tip with parallel lateral margins (expansion subquadrangular in shape); 177(1), reflection of the palatal tip of ~90°; 182(2), first upper alveoli do not overlap in level with second upper alveoli; 183(1) first upper alveoli completely anteriorized; 297(1), second upper alveolus aligned with third one (in the horizontal plane); 299(1), first upper alveoli strongly elliptical in shape; 301(1), third upper alveolus over twice as wide as the fourth one.
Anhanguerinae - 4 synapomorphies: character 100(1), anterior base of premaxillary crest tapered; 283(1), second premaxillary tooth apex extending anterior to first tooth apex292(1) mesialmost maxillary teeth relatively reduced (smaller than fourth premaxillary tooth and followed by markedly larger mid-maxillary teeth); 315(1), presence of a post-rosette toothline notch (in lateral view).
Ornithocheiridae - 1 synapomorphy: 57(1), rostrum tip with a ram-like anterior surface.
